CVE-2026-97540

Unknown

Last modified

CVE-2026-97540 is a vulnerability of currently unknown severity. In the Linux kernel, the following vulnerability has been resolved: net: usb: pegasus: don't rely on id table pointer arithmetic The current code is broken when dynamic ID is involved; in such cases usb_device_id parameter of probe lives on the heap and the pointer arithmetic will get an index that is wildly out of bound. Instead of keeping a side table for additional information, use driver_info field of the usb_device_id. The dynamic ID parsing code needs to be updated for this; convert it to just write to the reserved entry for dynamic ID and remove the weird loop..
